Bug ID: 85763
Summary: Feature request: Add a suggestion when compilation
fails dues to ambiguous templated friend function
Product: gcc
Version: unknown
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: joshua.r.marshall.1991 at gmail dot com
Target Milestone: ---
For friend functions with template parameters, it would be nice to have the
structure relation of typename'd values in a template declaration used for
function matching rather than what appears to be a more string literal
comparison or to throw a warning and suggestion when this is detected. For
example, have the following functions match or throw a warning:
> class my_class{
> public:
> template <typename _T>
> friend void func(_T val);
> };
>
> template <typename T>
> void func(T val)
> {
> ...
> }
It shows up as an ambiguous function definition, but one which seems very
help-able.
